Do I need spacers with JBA UCA's?

New poster, just picked up an 07 WK CRD with a 2" spacer lift. It came with 245/70/17 on moduflex wheels and they look kind of small. Thinking of adding a set of hardrock takeoffs with 255/75/17's. I am trying to avoid spacers and know about the ball joint bolt issue. And I have heard of upper ball joints failing with the spacer lifts. If I add JBA UCA's can I avoid the spacers? I plant to do the pinch weld, but I am not comfortable with spacers and had poor luck finding 7.5 or 8 inch wheels with the right amount of backspacing.

Re: Do I need spacers with JBA UCA's?

No. jba's actually make the stud more of an issue because the crown nut is in the way so you can't cut them. Also keep in mind that even if you clear the stud your gonna hit the inner wheel well on turns with that size tire. There's really no reason to be concerned about the spacers. Mine were on for 3 years untouched before I took them off to do the axles and they weren't easy to break free. I've put them through lots of abuse. Just don't cheap out in the spacer department. I took a picture of my jba CA to show you the ball joint. Also an example of what you'll hit with that size tire and no spacers. It's a metal edge and can rupture the tire.
